WebWhat is the difference between bulk flow and diffusion. Bulk flow movement is reliant on fluid pressure gradient, uses ATP to generate pressure gradient, works well over long distances. Diffusion flow by changes in concentration; uses thermal energy NO ATP, only over short distance. WebMolecular diffusion occurs in solids and in fluids that are stagnant or in laminar or turbulent motion. Eddy diffusion occurs in fluids in turbulent motion. When both molecular diffusion and eddy diffusion occur, they take place in parallel and are additive. Furthermore, they take place because of the same concentration difference (gradient).
